Title: Amino-substituted naphthalene derivatives
IPC: A01N39/00
Filed: 1967-07-25
Abstract: The invention comprises amino-substituted naphthalene derivatives of the general formula <FORM:1122756/C2/1> in which R1 and R2, which may be the same or different, are hydrogen, halogen, nitro, alkyl, alkoxy or trifluoromethyl; X is a straight- or branched-chain alkylene or alkenylene radical which may be substituted by an oxo or hydroxyl group; and -A-Y is a straight- or branched-chain alkyl radical substituted by a tertiary amino group; and the acid addition salts and quaternary ammonium compounds thereof. The tertiary amino group (Y) may be, for example, an alkylated amino group or the radical of a nitrogen-containing heterocyclic compound such as a pyrrolidino, piperidino, morpholino, piperazino, or imidazolino radical. The new compounds may be prepared by (a) reacting a naphthol derivative of the formula <FORM:1122756/C2/2> with a compound of formula U-A-Z in which U is a hydroxyl group or a hydroxyl group esterified with a hydrogen halide or an organic sulphonic acid, and Z is a tertiary amino group or a group which can be converted into a tertiary amino group; and converting the group Z if necessary to a tertiary amino group; (b) by condensing an amino-alkoxy naphthalene of the formula <FORM:1122756/C2/3> with a compound of the formula <FORM:1122756/C2/4> if the group X contains an oxo group it may be reduced to a hydroxyl group, dehydrated to give an alkenylene group and reduced to give an alkylene group, if desired; (c) by reacting the naphthol derivative of method (a) with compounds of formula U-A-U or the corresponding alkylene oxides to get intermediates of formula <FORM:1122756/C2/5> which can be converted to the required compounds by reaction with a base HY.  The basic compounds obtained may be reacted with inorganic or organic acids to give acid addition salts or with quaternizing agents to give quaternary ammonium compounds.ALSO:Amino-substituted naphthalene derivatives of the general formula <FORM:1122756/A5-A6/1> in which R1 and R2, which may be the same or different, are hydrogen, halogen, nitro, alkyl, alkoxy or trifluoromethyl; X is a straight- or branched-chain alkylene or alkenylene radical which may be substituted by an oxo or hydroxyl group; and -A-y is a straight- or branched-chain alkyl radical substituted by a tertiary amino group and their acid addition salts and quaternary ammonium compounds may be used as fungicides and for bactericides.

Title: Improvements in or relating to the reduction and sintering of moulded bodies containing reducible metal compounds
IPC: C21B13/00
Filed: 1947-12-29
Abstract: A method for the reduction and sintering of moulded bodies containing or consisting of reducible metal compounds is characterized in that the reduction is carried out in two or more steps in each of which the temperature is increased and for a predetermined period of time maintained within predetermined limits for permitting the escape of gases evolved in the reduction process to take place so slowly as to avoid formation of cracks in the body being treated.  The moulded body, having the shape of the finished article, is dried and reduced in a continuous operation either by a reducing gas or by a reducing agent mixed with the reducible compound or by both methods simultaneously.  The furnace used may allow continuous passage of the bodies being treated.  Plasticizers such as hydroxides, e.g. manganic hydrate or iron hydrate may be incorporated with the reducible compound to be moulded and moulding may be carried out by pressing in dies, extrusion, rolling or moulding on a carrier of paper or other combustible material.  Sufficient carbonaceous material for carburizing the product may be incorporated with the raw material. Subsequent to the reduction, presintering and final reduction operation may be carried out at a higher temperature followed by compacting and final sintering a temperature 50-150 DEG C higher than the presintering temperature and not lower than 80 per cent of the melting temperature of the metal concerned.  Compacting may be carried out by forging, pressing, hammering or rolling in the hot or cold state.  Specification 3926/97, [Class 72], is referred to.

Title: Improvements relating to containers for the aseptic storage of liquids
IPC: A61J1/00
Filed: 1960-10-11
Abstract: 912,220. Surgical storage containers. CHAPMAN, H. E. Sept. 21, 1961 [Oct. 11, 1960; Nov. 10, 1960], Nos. 34718/60 and 38567/60. Class 81 (2). A container for the aseptic storage of liquids comprises a container 1 with a closure assembly A. The latter comprises a dish-shaped lid portion 2 fastened to the container and having apertures 7, 7, 8. A rotatable member 14 fits into the recess 10 in the portion 2 and has holes 22, 22, 23 which, by rotation of this member, may be aligned with the holes 7, 7, 8. The holes 22, however, are associated with pads of a foamed plastic material which has been rendered germicidal and which, while preventing the passage of air will permit a hypodermic needle to be passed through them into the container. The member 14 is retained by a stationary plate 24 but is rotatable by an outer cap 28 by means of lugs 31 on the latter extending through arcuate slots in the plate 24. The air inlet 23 leads to an arcuate channel 18 in the plate 24 which is partially filled with filtering material 20, so that air has to pass through this from an external orifice 27. If desired, a similar arrangement B may be fitted to the base of the container but this is not provided with an air inlet. In cases in which the liquid must not be allowed to come into contact with air it is further proposed to employ a member in the form of a free piston, slidable in the body portion 1. This is maintained on the surface of the liquid and descends with it as it is withdrawn.

Title: Process of case-hardening metals and their alloys
IPC: C23C12/02
Filed: 1947-12-31
Abstract: A metal article, capable of cementation by carbon and silicon, is case-hardened by heating it in the presence of an organic silicon compond which contains at least one carbon atom of an organic radical united to silicon and which decomposes at the treatment temperature. The compounds used may be organo-silicon oxides, ethers and diethers, hydrides and chlorides, silicols or polymeric silicones and, by selection of the compounds the ratio of carbon to silicon may be varied.  The compounds may be decomposed on contact with the metal or previously decomposed or used in conjunction with a reducing or inert gas, which latter may also be used to produce a pressure higher than atmospheric.  The metal may be immediately quenched or cooled in air and reheated and quenched.  The silicon content may be over 7 per cent but a silicon of over 1.5 per cent and a carbon of not above 2.2 per cent in the surface is preferred.  If the silicon/carbon ratio is high free silicon may be deposited on the surface.

A PN junction silicon photo-diode 10, primarily for detecting solar radiation, has that part of the free surface of the N region 11 which is not covered by contact material 14, 15 coated with phosphoro-silicon glass. The glass has a refractive index approximately to the square root of the refractive index of silicon and its function is to reduce the reflectivity of the device. The device is formed from a body of P-type silicon which is either heat treated in an atmosphere containing phosphorus, e.g. phosphorus pentoxide and oxygen, or first coated with a phosphorus containing liquid, e.g. phosphorus pentoxide in water, and subsequently heated. The phosphorus diffuses into the silicon to form the N region 11 and also forms a phosphorosilicon glass surface coating 13. This glass is removed from the lower (P) surface by sandblasting, and from the edges and part of the upper (N) surface by chemical etching, a mask ing technique being used to control the extent of removal on the upper surface. The lower surface and exposed upper surface of the silicon are then solder-coated to form the P electrode 16 and a comb-like N electrode comprising the regions 14 and 15.
